In the Black-Scholes option pricing model, the value of a call is inversely related to: a. the risk-free interest stock b. the volatility of the stock c. its time to expiration date d. its stock price e. its strike price
Both call and put options are affected by the following five factors: the exercise price, the underlying stock price, the time to expiration, the stock’s standard deviation, and the risk-free rate. However, the direction of the effects on call and put options could be different.
Use the following table to identify whether each statement describes put options or call options.
Statement
Put Option
Call Option
1. An option is more valuable the longer the maturity.
2. A longer maturity in-the-money option on a risky stock is more valuable than the same shorter maturity option.
3. When the exercise price increases, option prices increase.
4. As the risk-free rate increases, the value of the option increases.
Select all that are true with respect to the Black Scholes Option Pricing Model (BSOPM)
Group of answer choices
When using BSOPM to value a stock option, the BSOPM assumes that stock prices follow a normal distribution.
When using BSOPM to value a stock option, the BSOPM assumes that stock returns follow a normal distribution.
Half of the observations in a normal distribution are above the mean and half are below the mean.
Fisher Black and Myron Scholes were awarded the Nobel Prize in 1997 for their work in Option Pricing.
